Definitions

  • the vortex of the cyclone device can be allowed to extend through the inlet all the way into the sluice wheel without disturbing the filling of the sluice with bulk material, which has the consequence that the length of the transition portion between the cyclone device and the sluice can be made relatively short.
  • the transition portion needs only be about four metres in length when sluicing bulk material in the form of fibres, which compared to a corresponding transition portion in a conventional sluice means a reduction in length of about 40%.
  • the sluice 2 is connected to a cyclone device for drying fibres (a cyclone device of this kind can have a dimension in height of more than 20 metres) , so that the lower narrow part of the conical separation chamber of the cyclone device communicates with the inlet 38 of the sluice 2 via a relatively short transition portion of about four metres.
  • the fibres are blown into the separation chamber of the cyclone device, so that a vortex of the mixture of air and fibres is generated therein.
  • the vortex extends through the transition portion axially down into the central free space 28 of the sluice wheel via the inlet 38.
